Mpower Communications Packages a Perfect Fit for Extra Space Storage [24th November 2003]

ANAHEIM, Calif., Nov 24, 2003 /PRNewswire-FirstCall via Comtex/ -- Mpower Communications Corp. (MPOW) , a leading provider of high-speed Internet access and local and long distance voice services, today announced that it has been chosen by Extra Space Storage to provide integrated communications solutions for ten of its locations in Nevada and California.

Extra Space Storage is a nationwide, state-of-the-art self-storage company that offers its customers the convenience and safety of storage units that include security systems, monitored surveillance and on-site management. Mpower's suite of broadband data products provide Extra Space Storage with a reliable solution to support the security and alarm system applications that are critical to its 24x7 operations.

"Having ten of our sites on Mpower's integrated voice and data product not only allows us to provide our customers with the quality of service they demand, but also has improved our inter-office communications and our ability to conduct our day-to-day business operations more efficiently," said Scott Stubbs, Vice President of Extra Space Storage. "Rather than multiple vendors for long distance, local telephone and Internet services, we now have one relationship with Mpower, which means one bill and a single point of contact that provides excellent customer service."

Mpower Communications' President of Sales and Marketing Jim Ferguson noted, "From our initial meeting at their Las Vegas location, we took the time to understand the special communications needs of Extra Space Storage's business and how Mpower could support its value proposition to its customers. After showing Extra Space Storage the reliability, flexibility and competitive advantage of doing business with Mpower, we are extremely pleased that they have extended the Mpower solution to a number of their satellite offices."
